No financial executives have gone to jail, despite an overwhelming body of evidence indicating that a group of organized “banker gangs” conducted a widespread Wall Street crime wave that made them rich and while throwing millions into poverty. The Justice Department’s failure to act against these bankers is matched only by its declining credibility — a problem it only makes worse whenever it tries to defend itself.

An interview with an outgoing Justice official in today’s Wall Street Journal is merely the latest in a sad parade of weak excuses and implausible arguments, and it comes on the heels of Justice Department official Lanny Breuer’s poor 60 Minutes showing this week on the same topic.

Stop. Just stop. If nobody at Justice can get the job done, it’s time for the Administration to bring in a whole new team and start again. Did everybody in the banking business break the law? No. Very few did. But some of the ones that did appear to be very well-placed, and if they’re not punished they’ll do it again and again.
